John McLean, Meegan v. Boyle — Opinion of the Court
“ But whether it be a genuine instrument or not, it has not been treated as valid, as no claim has been set up under it, and all the heirs have acted, in regard to the estate of their father, as though he had died intestate.Neither the deed to Chouteau, nor the will, can be admitted in evidence, without proof, as an ancient instrument. The rule embraces no instrument which is not valid upon its face, and which does not contain every essential requirement of the law under which it was made. ”
